Markup AI

Markup AI keeps your content clear, on-brand, and compliant — right inside Google Docs. Writers shouldn't have to memorize dozens, sometimes hundreds, of brand guidelines. Configure your brand standards once in the Markup AI console, and the extension's agents apply them automatically every time you write. All it takes is to upload your brand guide and a few links to content you love, and Markup AI will tailor every suggestion to your voice, tone, and brand terms.

Open the side panel, run a check, and Markup AI gives you instant, actionable feedback — catching what's off-brand, off-target, or using the wrong terms, with a one-click fix for each issue. Apply the rewrite, add it as a tracked suggestion, or leave a comment for someone to review, all without leaving your document.

The extension runs the full set of Markup AI agents. The core ones:

* Brand Voice — Finds content that doesn't sound like your brand.

* Brand Terms — Replaces off-brand and unapproved terms with preferred alternatives.

* Persona — Catches content that doesn't resonate with your intended audience.
